I don't see tryhard being a bad thing. I personally take it as a complement for being better at the game than someone else. As for not trying at a video game, is like not trying to get a job and just hope something goes your way instead of making something go the way you want it.

and anyone who just plays video games and doesnt care if they win or lose, there is something wrong with them, it means you are either ugly, cant get a girl, or suck at sports and are used to being mediocre
